33、3GPP TS 29.238 version 13.1.0 Release 131 Scope The present document describes the protocol to be used on the Interconnection Border Control Function (IBCF) Transition Gateway (TrGW) interface and the CS-IBCF CS-TrGW interface. The basis for this protocol is the H.248 protocol as specified in ITU-T.
34、 The Profile provides MG control function for IMS and CS Border Control. The IMS architecture is described in 3GPP TS 23.228 2. The underlying reference model and stage 2 information is described in Annex I of 3GPP TS 23.228 2 and in 3GPP TS 29.162 18. The CS architecture is described in Annex A of
35、3GPP TS 29.235 17. This specification describes the application of H.248 Ix profile for both Ix and CS-Ix interfaces (see Figure 1.1 and Figure 1.2). Required extensions use the H.248 standard extension mechanism. In addition certain aspects of the base protocol H.248 are not needed for this interfa
36、ce and thus excluded by this profile.

Figure 1.3: Reference model for IBCF/TrGW with ATCF/ATGW function See 3GPP TS 23.237 38 subclause 5.2 for a comprehensive
39、description of the reference model. NOTE: The Ix profile is applied over both IMS and CS Ix interfaces.
